,il-g all 'whom 'it m ag/ con com lie it known that l, RUSSELL E. TAYLOR,

citizen of the United States, and 'a resi--v :lent of the borough of Manhattan, city, enmity, and State of New York, have inrented. a new and usefulmprov'ement in' Ziottle-Capping Machines, of which the foliowing isa specification.

My invention relates to bottle-capping machines, sometimes spoken of 'as bottle sealing machines, and has for its object to provide a machine, operable. by hand or automatically, in which the strains produced in the bottle structure incident te the capping operation .are confined-to 'the neck of 'the bottle instead of'being distributed as heretofore throughout the entire structure;

i a further object ot' my invention is to provide a bottle capping machine applicable to bottles having short necks in contradistinction to machines requiring that the bottles jto be capped should have relatively long i necks; a still further object of my invention is to provide a bottle capping machine caypa-ble of capping thin walled bottles with as little'risk of breakage as when capping thick I walled bottles; other incidental objects will appear as the specification proceeds.

` Essentially my improved bottle capping Referring to the drawings, which are hereby made a part. of the specification, Figure 1 represents a side elevation, part-ly in section, showing a preferred embodiment of a complete machine made according to my -invention Fig. .2 represents an enlarged @iront elevation showing the capping and vsumiorting mechanism proper of my machine; Fig. 3 is a plan'view taken along the line of Fig. 2, Fig. 4 represents a simithe machine.

lai-ly enlarged vertical sect-ion taken along the line 4 4 of Figs. 2 'and 3;` Fig. 5 repre- 'vsents a. transverse diagran'imatic sect-ion taken along the line`5-5 of -Fig.4 and shows t-he capping and supporting mechanism just before capping takes place; and

Fig. 6 is a view, similarto Fig. 5', showing the position of the capping and supporting mechanismjust asthe capping is complete and before the bott-le hasbeen removed from Fig. 7, is a detail sectional` view showing certain modified features, and

Figa 8, is a plan view of the same.

'In the drawings (F igsvl to 6 inclusive) there is a `main` frame comprising a base castingtupon which is erected aA tubular support 2 which carries a table 3 at convenient heightand is surmounted by a. head A frame 4.

As illust-rated7 a connecting rod is joined to a treadle 6, which in turn is pivoted to the base at 9, so that the connecting' rodl is depressed when'the treadle is depressed. The

connecting rod 5 is flexibly connected to an actuating rod 7 in linewiththe connecting rod and .slidable in bearings 9 and 10 'of the trame, see particularly Fig. 1. At the upper end of this rod are stop-nuts 8, which limit the downward movement of the rod.f

The connecting rod 5 'is provided, at a convenient distance from its upper end, with a screw thread upon which is fitted an ad justable abutment 11 Aand at some distance below this abutment is another adjustable abutment 12. screw threaded to the interior of the tubular support 2 and centrally bored Vtopermit the connecting rod to easily -slide within it. A suitable spring 13 surrounds the rod 5 between the two abutments4 11 and 12. v

Within the headframe 4 and fixed tothe actuating rod by screws 14' is a capping head 15 comprising essentially a pair of short cylindrical portions joined by a web or neck,

the` rear cylinder being the smaller. The

front and larger cylinder 15 projects through an opening in the head frame andr is provided with lateral guides l16 adapted to slide in corresponding grooves Jformed 1n said head frame. This front cyllnder 15 of the capping head is axially bored through I to receivea bushingltsweatedor o thervt-'ise permanently fixed therein and in this-'bushing is a s nare bottomed cylindrical "recessL recess 18,1554 solenoid 23; a short'spindle-24 .is fixed to the top of the-solenoid 'and eX- tendingF upwardly toward .the plug 19... A

spring` 25` surrounds this spindle-and is'supported upon Vthe solenoid `with its 'other 'end restingvagainstthe plug.

Fixedtothe. top of the solenoid is a statt 26 to which'isjoined oneend of the solenoid winding, the .other end ofsaid'winding being- 'grounded to the plunger. A spring 27-tixed to the inner walllo"I recess 42518 conta-cts with said statt' and constitutes ari-'endet a battery'circuit 28 the other hat# -the mainframe of the machine. An usual ,electric light or power' circuit mayibe vused .30' to energize the solenoid instead-of aba-ttery porting o r 'bottle hold-ingv jaws 30. The'im nei-"end 'otA leach jawxis concave centrally 'and 1s furtherprovided with a pi'votally a ttachedllink 31, the outer endsof which are joined by a. common polnt to a centrallydisposed Vrod 32 which is'slidable forwardly or rearwardly in a lug 33 iixed to head 'franje 4;.upon the rear end of rod 32 is; an adjustable screw nut 34. Bymeans ofV the two links 31 and the rod 32 the inner ends of jaws 30. may be n 'ioved in or out with yrespect to the head frame but must .move to-. gether and `soas vto make 'it all times'equal fa-ngles with said frame. T -e adjustablenut 34 limits the extent of such movement.

' A second pair'of bosses .35 is arranged below the jaws 30 and located nearer the position of the bottle during the capping' action; they serve' asreintorcing supports sure of the bottlecapping operation to be shortly c lescribed.- Both pairs otbosses as, -al'so the top and bottom of the jaws 3() aref machinedlat so as to permit the adjacent surfaces to `lit closely and to. engage their entire areas.'

A bottle, that'it may-'be -c appedwith a .machine made Aaccording to my invention as shown in Figs. l'to 6j; must have its neck proyided with' a suitable bead or enlargebottom of this recess-is a straight cylindrical 2O which. is gradually enlarged' as 'it for said ia-ws toresistthe 'downward presoverment 3 6 the jaws being vso set and ofsiich length as to just comfortably embrace' the 'vec'k proper'bcloi-irv said bead when. said jaws are in bottle capping position against vthe head frame. The shape 'of this bead should Abe ich asto' afford ample strength for resisting the-downward pressure of the'bottle capping operation and itmnst join. the neck proper sufficiently below the-top thereof to give' the capping head room' to do'its work as will hereafter appear. Above'the bead 36 and-preferably at the -iery top of the bottle :neck is a capping. bead 87 against and under which vthe edgesof the cap 21 are to -be forced'. I f The operation of my improved bottle .capping machine. is as follows:--Tlie jaws 30A being drawn forwardv (dotted 'construction two 'aw ends the bead 36 bein r ab'ovethe l i l .fh .s

jaws; ifthe, concaves ot tnese- Jaw' ends are suitably determined the bott-le neck will enter thejaw opening when thev jaws are thus in tiei'r outward 'position but will not passthiigh the same. The bottleisthen pushed rearwardly which will cause the jaws to close againstthe head frame and bring the'bottle'neck inuneditely under 'the .plunger 22." Simultaneously with thisopleration a.. bottle'cap'tof lsoft iron or other magnetic` I natferial) 21 is thrust into the opening :it-fthe bottom .of pluuger'22iand willbe held against said plunger by reason of the magnetization 'providcdby solenoid' 23. .Foot'treadle 6is then depressed causingthe actuating rod/7 with the attached capping' head 15 to be drawn-,downwardly against the resistance of spring' 13 by reason of the connectinfrrod; llu'nger 22 and the bottle neck being 4in ,axial alinement. the bushinf,T 17 'will bedrawn down over `the hott-le neck and' plunger 22 pushed upwardly into the tapered opening ot the lnishingv againstl the resistance of' spring! until stopped by the`check uutsS contacting with the head frame 4. the plunger aseends the cap 21 willbe pushed into a narrower region'of the taper and' will have its dcpeudent edges crimped over the 'capping' bead 37 ot the bottle neck., The foot treadle t3 is then released when thegappingr head will rise h v reason of the action of spring' 153 and plunger 22v again descend iu bushing 17 rer-.dy to receivea 'Fresh cap. 'lhe capped bottle' is then drawn forward and removed. the jaws 5:30 azonline tm'ward with the bottle until limited-bv` the vadju-.etable nut 'lhe arrzmgement. ot heads. tv aud 37 shown in tlxesevcral figures above described is the usual one provided for bottles which are tobe capped with metallicwaps or seals of the general' type indicated at 2l. Bot-A tles intended to be corked merely, sueltas.

Fig. 3) a bottle is `grasped in the hand and its neck thrust tinto the opening between the los - with. my improved machine I. need only substitute tortheform oi'ineclsupporting aws shown in Figs. l to 6 the modifiedjaws 30 of Figs. 7 and S which have their inner' ends each provided with an upwardly and centrally inclined bead supporting'ton'gue 32 of wedge shaped section; the tops of these tongues are adapted to snugly embrace the bottle neck proper 'just under bead 37 when the bott-le is in capping position. very thin at their tops and lying close to the bottle neck'throughout their entire height,

as they preterably'should, these tongues willnot interfere with the descent of the capping head noi;l with perfect crimping 'of the edges of the .b'ottle` caps about the bead 37. -W'here a machine is to be used permanently for capping` bottles of uniform size, or rather, bottles having necks of uniform size the bushing 1'( may beljmade an integral part of the front cylinder 15 of. the capping head the necessary holes and openings toreceive plunger 22 being formed directly in said cylinder. Obvious mechanical reasons, however, made the separate bushing construction preferable.

y l-Vhere. it is desired to adapt one of my improved machines to bottles having a neck of given size instead of somo other size I need only to exchange the Jaws 30 for others haring appropriate sized inner ends and the bushing 17 with its plunger 22 and associ ated solenoid for another bushing provided with a plunger ofi-appropriate size. Where the plunger is thus to be removed or eX- changed at. times it may preferably be held in place by a set-screw 8S rather than sweated or similarly fixed as previously described..

Wrhile I have described my invention as a manually operated machine it is vclear that,` by obvious mechanical adaptations` it may be readily converted into a continuously acting power operated or automatic machine.

.My improved bott-le capping machine enables me to cap thin walled .bottles as readily as thick walled bottles and short necked bottles as readily as long necked bottles; bottiles having necks `ioin'ed to the body by reentrant portions and other bottles of odd .shape not adapted to usual bottle capping machines may readily be capped Withmy machine.

Should breakage take place-in the, operation of my machine such breakage will be confined to the neck of the bott-le and the contents thereof will not be spilt over the machine and operator as is necessarily the case with machines in which the-bottle is supported upon its base.-

While I have shown and described a spe- Being cifieform `of my invention I .do-'not confine myself to the detailed embodiments setl orth' many of which may be varied Withoutv depart-ing from the spirit of my. invention. Thus the character. and mode voi operation of the neck supporting jaws, the detailed y means by' which' the cap is held againstthe .s plunger Q theexact means by which the bottle neck is forced into .the cappinghead and many other` details may be and may require to be altered to suit special needs for which the machine. isjdesired to be used Without going beyond the-essence .ot my invention which I have embodied in 'the ol-` lowing.
